摘要
分析了包过滤防火墙的工作原理,然后在对W indows NT和Linux内核网络接口的分析基础上,通过修改操作系统的内核,实现了透明的包过滤防火墙.并对包过滤防火墙提出了自己的见解.
The working principle of packet filter firewalls is analyzed first. Based on analyzing Windows NT and Linux kernel NDIS, the transparent packet filter firewall is implemented by changing operating system kernel. Finally, this paper gives some advice on packet filter firewall.
